redmine默认是用webrick启动的，这种方法不适合生产环境，最好部署在apache下，本文介绍如何通过mod_fcgid启动。
首先要有一个能够启动的redmine，可以通过我之前的博文查看： http://www.cnblogs.com/wzy5223/p/5335549.html
本例redmine的安装位置：/opt/redmine-3.2.1
一. 下载资源
wget http://mirrors.hust.edu.cn/apache//httpd/httpd-2.2.31.tar.gz
wget http://mirrors.hust.edu.cn/apache//httpd/mod_fcgid/mod_fcgid-2.3.9.tar.gz
二. 编译apache
tar xzvf httpd-2.2..tar.gz
cd httpd-2.2.
./configure --prefix=/opt/httpd-2.2. --enable-rewrite
make
make install
三. 编译mod_fcgid
tar xzvf mod_fcgid-2.3..tar.gz
cd mod_fcgid-2.3.
APXS=/opt/httpd-2.2./bin/apxs ./configure.apxs
make
make install
四. 配置redmine到apache
cd /opt/redmine-3.2./public
cp dispatch.fcgi.example dispatch.fcgi
cp htaccess.fcgi.example .htaccess cd cd /opt/httpd-2.2./conf
vi httpd.conf
找到下面的内容
DocumentRoot "/opt/httpd-2.2.31/htdocs" #
# Each directory to which Apache has access can be configured with respect
# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories).
#
# First, we configure the "default" to be a very restrictive set of
# features.
#
<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
</Directory>
修改为
DocumentRoot "/opt/redmine-3.2.1/public" #
# Each directory to which Apache has access can be configured with respect
# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories).
#
# First, we configure the "default" to be a very restrictive set of
# features.
#
<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Allow from all
</Directory>
并修改监听端口为3000
Listen
五. 安装mod_passenger
gem install passenger
yum install libcurl-devel
passenger-install-apache2-module --apxs2-path /opt/httpd-2.2./bin/apxs --apr-config-path /opt/httpd-2.2./bin/apr--config --languages ruby
上面的命令最后会有一段字符需要添加到httpd.conf，例如下面
LoadModule passenger_module /home/wzy/.rvm/gems/ruby-2.2.4/gems/passenger-5.0.26/buildout/apache2/mod_passenger.so
<IfModule mod_passenger.c>
PassengerRoot /home/wzy/.rvm/gems/ruby-2.2.4/gems/passenger-5.0.26
PassengerDefaultRuby /home/wzy/.rvm/gems/ruby-2.2.4/wrappers/ruby
</IfModule>
六. 启动apache，测试是否能访问 http://<IP>:3000
/opt/httpd-2.2./bin/apachectl start
如果能成功访问就大功告成了，最后可以将apache添加到服务，就可以随系统重启了
